.SH Synopsis

   reverse_iterator rbegin();                       \fB(1)\fP (noexcept since C++11)
                                                        (constexpr since C++20)
   const_reverse_iterator rbegin() const;           \fB(2)\fP (noexcept since C++11)
                                                        (constexpr since C++20)
   const_reverse_iterator crbegin() const noexcept; \fB(3)\fP \fI(since C++11)\fP
                                                        (constexpr since C++20)

   Returns a reverse iterator to the first character of the reversed string. It
   corresponds to the last character of the non-reversed string.

.SH Parameters

   \fI(none)\fP

.SH Return value

   Reverse iterator to the first character.

.SH Complexity

   Constant.

.SH Notes

   libc++ backports crbegin() to C++98 mode.

.SH Example


// Run this code

 #include <algorithm>
 #include <iostream>
 #include <iterator>
 #include <string>

 int main()
 {
     std::string s("Exemplar!");
     *s.rbegin() = 'y';
     std::cout << s << '\\n'; // "Exemplary"

     std::string c;
     std::copy(s.crbegin(), s.crend(), std::back_inserter(c));
     std::cout << c << '\\n'; // "yralpmexE"
 }

.SH Output:

 Exemplary
 yralpmexE
